Specification of Letters Patent.

Application filed August 4, 1919. Serial No. 315,056.

To all to 7mm it may conccm v i w a lie it known that l, 'inaononn (i, b'rua'rnu,

Fig. 2 is a vertical longitudinal sectional view oi: the valve illustrated in Fig. 1, the

a citizen of the United States, and resident locking member being shown in elevation,

of Brookline, county oi. Sutl'olk, State of Massachusetts, have invented an Improvement in Faucet-Locks, oi? which the iollowing description, in connection with the accompanying d awing, is a specification, like characters-5 on the drawing representing like parts.

Th1s 1n vention relates to improvements lIl alve locks and the object thereof is to pro-' vide an improved valve lock which will be of more rigid construction and more efficient in operation than those heretofore constructed. Valves provided with locking means are particularly desirable for use in connection with stoves, heaters and lighting jets which can be caused to lock the valve in closed position so a to prevent an improper escape of the gas.

Many of the locking devices for valves gas pipes which lead to burners tor heretofore constructed have been of such light and delicate construction that they have been readily broken and thus rendered ineffective. One of the principal objects of the present invention is to provide a valve lock in which the locking member will be of a strong rigid character and so protected or inclosed, preferably in the valve stem, that it will be out of the way of injury so that when used upon the pipe leading to a heater which may be adjacent the floor the valve will not be likely to be damaged even it struck by the foot or by objects being moved around in the room.

A further object of the invention is to provide a valve lock of the character described in which the spring which actuates the locking device will be inclosed and pro- Fig. 3 is a plan view of the valve casing.

The valve shown in Fig. 1 has a valve casing 1 which is provided with internal screw threaded ends 2, 3 by means of which it may be connected into the usual pipe line but which of course may be provided with a nipple to form a. connection for a rubber tube. A casing 1 is provided with a transverse, pretcrably conical aperture at which forms a seat for the valve plug 5. The valve casing desirably is provided adjacent the upper end of the aperture with an annular boss 6 which has one or more recesses 7, 8 communicating with the aperture 4, said recess being adapted to receive a locking memher and positioned in such a manner as to lock the valve in closed position and such other adjusted position as may be desirable preferably including the wholly opened position as shown in the drawing.

The valve plug 5 has a vertically chant bercd stcm9 WhlCll has a transverse slot 10 extending therethrough. The valve stem 9 desirably has adjacent the sides of the slot laterally extending bosses 11 to receive a stud or shaft 12 forming the pivot for the locking member 13. The locking member 13 may be in the general form of a sector having its curved portion 14: lying closely adjacent the lower wall 15 of the slot 10. The end portion 16 of said sector is so positioned that it will engage the recess 7 or 8 when positioned thereover. In order to operate the locking member a preferably integral handle 17 is provided which extends alongside the valve stem. A spring 18 inclosed in the chambered stem engages the upper edge 19 of the locking member and tends normally to force the locking portion 16 into engagement with the recess. The spring 18 desirably is secured in the chambered stem by means of a screw 20 which is seated in the upper end of the chambered stem and bears upon the upper end of the spring 18.

.lt is desirable to provide means to limit the rotation of the valve to a quarter turn which will. permit it only to move from closed to open position. Means accordingly have been provided for restricting the movement of the valve, such means comprising an extension 21 oi said locking member which is adapted to engage lugs 22, 23 ex- 'tending upwardly from the annular boss 6 and so disposed as to arrest the locking member 21 when the valve is either in open or closed-position.

V The valve stem 20 may be providedwith any suitable form of operating means such as wings 24. In order to hold the valve in its seat the lower end of the valve has the usual screw threaded extension 25 which asses through a' washer 26 covering the lbwer endof the plug aperture,'a spring 27 being interposed between said washer and one of a pair of check nuts 28, 29 secured upon the end portion of the extension.

In operation the valve is normally held in the locked position illustrated in the drawing. When it is desired to rotate a valve for the purpose of turning on the gas or other fluidwhich is to flow through it the operator clasps the wing 2a with the fingers and with thethumb presses upon the lever 17 of the locking member. The locking member-is thereby rotated about its'pivot I 12 until the portion 1 9 is withdrawn from the recess v16 whereupon the valve can be r0 "tated any desired distance to turn on as dle 17.

When the locking handle is depressed by "the operator to the dotted line position illus tratedin Fig. 2 the'extension 21 of the looking memberi's'brought down closely adjacent to the boss "6 so that it'will unfailingly --engage"the projection 22 or 2321s the valve plug is'rotated thereby limiting the rotation of the valve as above described.

It will be'understood that the embodiment ofthelinve'ntiondisclosed herein is illustrative and not restrictive and that various "changes in construction and arrangement of parts may be made within the spirit'and scope of the following claims.

Having, thus described my invention what I'claim as new and desire to secure by Letters Patent is V 1. A valve comprising a valve casing, a

ing a plug aperture and a locking recess communicating with said aperture, a plug rotatably mounted in said aperture having a stem provided with a hand piece and having a transverse slot extending through said I stem, a locking member pivotally mounted in said stem extending through said slot and having means to e age said recess and provided with a ha dle extending alon ide said hand piece and resilient means inc used in said stem above said locking member engaging said locking member tending normally to force the locking member into engagement with saidrecess.

In testimony whereof, I have signed my name to this specification.
